Electromagnetic coils are devices made from a winding of wire that creates a magnetic field when an electric current passes through it. The primary principles governing electromagnetic coils are based on electromagnetism, which describes the relationship between electricity and magnetism. ### Key Features of Electromagnetic Coils: 1. **Structure**: Coils are typically made of conductive materials, such as copper or aluminum wire, wrapped around a core, which can be air or a ferromagnetic material like iron.
